Notes:

Browse source 
+ The MPU port is not supported in this revision number.
+ The documentation for the static allocation functions in the header files has not yet been updated for this revision.

Kernel updates:
+ Simplify the static allocation of objects implementation.
+ Introduce configSUPPORT_DYNAMIC_ALLOCATION in addition to the existing configSUPPORT_STATIC_ALLOCATION so FreeRTOS can be built without providing a heap at all.

Demo application updates:
+ Update the demos to take into account the new configSUPPORT_DYNAMIC_ALLOCATION constant.
+ Add an MSVC demo that only uses static allocation, and does not include a FreeRTOS heap.
+ Update the MSVC project to use both configSUPPORT_STATIC_ALLOCATION and configSUPPORT_DYNAMIC_ALLOCATION.
+ Update the MingW project to use only configSUPPORT_DYNAMIC_ALLOCATION.
